The reasons why the electronic control engine computer ECU cannot monitor the failure are as follows.
(1) Under normal circumstances, the ECU of low-end cars cannot monitor the failure of the ignition coil, the pollution or damage of the spark plug, and the failure of the high-voltage ignition circuit caused by the broken core of the high-voltage line.
(2) The ECU cannot monitor the electric gasoline pump oil inlet filter, fuel filter pipeline blockage, and the oil inlet pipeline or return pipeline is flat and the oil inlet pipeline is not smooth.
Smooth, or the mixture is too thin. The rearview mirror of Mercedes-Benz car is loose
(3) The ECU cannot monitor the air filter inlet or the air filter is blocked or throttled. Solutions to faults or vibrations caused by changes in air flow. Product Brand Summary Mercedes-Benz Maintenance and Repair Common Accessories
(4) ECU cannot monitor the level of cylinder pressure or the uniformity of each cylinder pressure
(5) The ECU cannot monitor the damage of the plug and pin, but it will generate a fault code caused by this condition (6) The ECU cannot monitor the poor grounding, but it will generate a fault code caused by this condition
(7) The ECU cannot monitor the leakage or throttling of the vacuum line of the vacuum booster in the engine control system. However, the vacuum of the intake manifold absolute pressure sensor will be monitored, and the ECU will also record the fault code.
The above 10 items are the causes of failures that cannot be detected by the electronic control engine, and attention should be paid to them when repairing the electronic control engine. Whether it is an electronic control failure or a mechanical failure, it is necessary to correctly distinguish the location and performance characteristics of the occurrence in order to accurately and quickly judge and troubleshoot
During the inspection, if the engine fails and the engine failure warning light does not light up (the failure code is not displayed), it means that the engine failure may be in the mechanical part.
